1 Environment, Safety&Health Quarterly Performance Report Reporting period: 1 April to 30 June 2015 Welcome to AWE s second quarterly performance report for This document is designed to inform you the local and wider public of our management of the environment, safety and health at our sites in Aldermaston and Burghfield. Whether in support of nuclear processes or operations, or those things we do as part of our everyday working lives, the environment, safety and health underpins all our activities. The safety of our employees, our community and the protection of our environment is and will always be our highest priority. News this quarter AWE continues to deliver its commitment to reducing waste and promoting reuse and recycling over landfill disposal. Approximately 95% of all waste generated by AWE is construction and demolition waste. Typically over 90% of this waste is reused or recycled, exceeding the target of 80% waste diversion from landfill and moving towards the ultimate goal of zero waste to landfill. AWE Head of Environment, Peter Caddock, said: A number of recent projects have successfully combined to reuse both waste concrete and subsoil. This has included over 2,000 tonnes of waste concrete crushed and reused on site, and over 3,000 tonnes of subsoil. The result is that we are much more sustainable and we are making effective and efficient use of all resources. Further benefits of this approach are a reduction in the volume of material sent off site for recycling and a reduction in the amount of vehicle movements to and from site. This is leading to reduced emissions and a smaller carbon footprint. In addition to the positive impact on the environment, there have also been considerable cost savings to these projects. Congratulations to Emcor, one of AWE s main suppliers, for winning the Royal Society for the Prevention of Accidents (RoSPA) Award, in recognition of Emcor s environment, safety and health performance across our sites. 1

2 Public dose data AWE monitors discharges of radioactive material from its sites and assesses the impact these could have on the local environment and the public. The table below shows the rolling annual dose to members of the public from Aldermaston and Burghfield discharges. The calculated doses represent minute fractions of the dose constraint set by the Environment Agency of 500 μsv per year for a nuclear site. The assessment concludes that there is no hazard to the public. Public Dose Assessment Discharge Aldermaston Burghfield Guidance Levels Q Jul 2014 to Jun 2015 Q Jul 2014 to Jun 2015 Atmosphere Less than Less than 0.03 μsv 0.10 μsv μsv μsv 500 μsv Trade Effluent μsv μsv 500 μsv Aldermaston Stream μsv μsv 500 μsv Refer to list of definitions of units of measurement at the end of this report.

Anyone working on AWE sites or carrying out company business off site are required to make a report, through recording on the AWE reporting system. These incidents are referred to as Abnormal Events. We believe that lessons can be learnt from even the most minor incidents and those lessons can help prevent more occurrences from happening in the future. With this in mind, we also have a system called Assurance Observation Reports which allow people to engage and capture conversations around safety on a daily basis. 2

3 How we report on our industrial safety performance Certain Abnormal Events are automatically reported to the Health and Safety Executive (HSE) under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR). RIDDOR is the statutory legislation that requires employers, and other people who are in control of work premises, to keep records of certain Abnormal Events. No RIDDOR reportable events have occurred during this quarter. The number of RIDDOR events reported during the preceding 12-month period appears in the chart below. RIDDOR Total Reportable Incidents by number of events in month and rolling 12-month rate Number of incidents Rolling 12-month rate per 100,000 hours worked 0.02 Target = Zero 0 Number of incidents in month Rolling 12 month rate Jun 14 Luly 14 Aug14 Sep 14 Oct 14 Nov 14 Dec 14 Jan 15 Feb 15 Mar 15 Apr 15 May 15 Jun

4 How we drive improvement in our performance AWE is committed to a continuous programme of improvement, and as part of further learning we also use the United States Occupational Safety and Health Administration (OSHA) system when applying a classification code to injury and illness related Abnormal Events. The chart below shows AWE s performance for all OSHA recordable events by Contract Year OSHA Total Recordable Incident Rate (TRIR) by Contract Year OSHA TRIR per 200,000 hours worked Trend over time Target = Zero CY9 CY10 CY11 CY12 CY13 CY14 CY15 CY16 to date TRI Rate How we report on our nuclear safety performance In addition to reporting events to the HSE under the RIDDOR regulations, as a nuclear licensed site, AWE has also set criteria for which incidents must be reported to its nuclear regulator, the Office for Nuclear Regulation (ONR). Events reported to the ONR during the current reporting period are listed in the table on page 5. Where applicable, an indication of the International Nuclear and Radiological Events Scale (INES) rating, given to the event, is also listed. The INES scale is used by nuclear operators to give a common international standard for comparison of nuclear events; these events are rated on a scale of one to seven. Those coded as zero are deemed below the scale and to have had no safety significance. Those coded TBC are subject to findings of ongoing investigations. Those coded N/A relate to events that fall outside the INES rating criteria. 4

5 ABNORMAL EVENT All events occurred at AWE Aldermaston unless specified otherwise Protecting our environment In order for AWE to operate our sites and perform our role in national defence, we are required to hold a number of permits, authorisations, registrations, licences and consents. We have to apply to the appropriate regulators in order to be granted these permits, authorisations, registrations, licences and consents (jointly termed permits). Environmental events notified to the Environment Agency All events occurred at AWE Aldermaston unless specified otherwise. April 2015 An elevated reading of 233 nbq/m³ for plutonium was recorded from a High Volume Air Sampler (HVAS) located at AWE Aldermaston (a becquerel (Bq) is a measure of radioactivity). The elevated reading is the result of low levels of legacy waste during demolition activities. The sample taken exceeded the notification level of 100 nbq/m³. It should be noted that whilst the level required us to investigate the event and notify the Environment Agency (EA) and the MOD, the estimated dose was very small and not at a level that would pose any harm to the public or the environment. We notified the EA that one of the milk farms listed within our environmental monitoring arrangements had ceased to operate as a dairy farm with effect from 10 April As a result, AWE would be unable to fulfil the requirement to collect this milk sample in April 2015 and would no longer be able to obtain a sample from this location. The EA were content for AWE to sample from other farms within the vicinity of Aldermaston and not find a substitute farm. May 2015 Initial/ Provisional INES Rating Final INES Rating April 2015 No reportable events - - May 2015 Decommissioning process was identified as non-compliant with requirements 0 1 Following review, further assessment of the contents of a coolant tank is to be undertaken TBC TBC June 2015 Glove in the glovebox found to be damaged. Monitoring was undertaken and full access restored 0 TBC We notified the EA of our intention to increase the sampling frequency for specified air samplers from monthly to fortnightly to help with an investigation into elevated levels of tritium. The investigation into the cause is ongoing, but the increase is not at a level that would pose any harm to the public or the environment. The notification was required as the samplers are identified within our environmental monitoring arrangements and any changes require notification. The increased sampling frequency was approved by the EA on a temporary basis for three months with effect from 28 May June 2015 An elevated reading of 241 nbq/m³ for plutonium was recorded from a HVAS located at AWE Aldermaston. The elevated reading is the result of low levels of legacy ground contamination. The sample taken exceeded the notification level of 100 nbq/m³. It should be noted that whilst the level required us to investigate the event and notify the EA and the MOD, the estimated dose was very small and not at a level that would pose any harm to the public or the environment. 5

6 Waste minimisation As part of AWE s commitment to protecting the environment, we have a long-term vision to become a zero-controlled waste-to-landfill organisation, details of which are given in AWE s Annual Review of Sustainability (available on AWE s website). To that end, there is a drive towards minimising waste and avoiding landfill wherever possible. AWE monitors diversion from landfill, for which a target of 80% has been set for Controlled, and Construction and Demolition waste. Controlled Waste Normal operational waste but excluding radioactive (RA), Explosive, and Construction and Demolition Construction and Demolition Waste Commonly rubble and soil but excludes Controlled, RA and Explosive Reused An item to be reused on site, or resold to be reused in its original condition Recycled An item that can be broken down and made into something else Recovered Where waste is burnt and energy recovered, or waste is used in land remediation Disposed Where waste is not reused, recycled or recovered Below are the performance statistics for this quarter. Diverted from Landfill % Reused % Recycled % Recovered % Total diverted from landfill % Disposed Controlled 10.4% 54.9% 22.9% 88.2% 11.8% Construction 11.3% 77.4% 10.6% 99.3% 0.7% The target is to divert 80% of waste away from landfill. 6
